The word 'assess' comes from the Latin verb 'assidere' meaning 'to sit with'. In assessment one is supposed to sit with the learner. This implies it is something we do 'with' and 'for' students and not 'to' students.
Assessment for learning is an on-going process that is at the heart of teaching and learning. In order to provide instruction that meets the needs of our students, a teacher must know what students understand and where they are in their learning. The information the teacher gathers is used to adjust teaching and learning in ways that help students move forward.
